  • Climate Change Increases Flood Risk in Peru

    The rising danger of glacial lake flooding in a warmer climate has important implications for humans and animal populations in Peru’s Cordillera Blanca. A recent study in CATENA by Adam Emmer et al. examined a large swath of nearly 900 high altitude Peruvian lakes in the mountainous Cordillera Blanca region, studying their susceptibility to outburst floods…

  • Roundup: Tragedy in Antarctica, Antimony and Glacier Risks

    Roundup: Tragedy, Antimony and Risk   Prominent Climate Scientist Dies in Antarctica New York Times: “Gordon Hamilton, a prominent climate scientist who studied glaciers and their impact on sea levels in a warming climate, died in Antarctica when the snowmobile he was riding plunged into a 100-foot-deep crevasse. He was an associate research professor in the…

  • New Study Offers Window into Glacial Lake Outburst Floods

    A recent geological study has shed some light on the cause of a major, yet elusive destructive natural hazard triggered by failed natural dams holding back glacial lakes. The findings show how previously unrecognized factors like thinning glacier ice and moisture levels in the ground surrounding a lake can determine the size and frequency of Glacier Lake…

  • First global analysis of the societal impacts of glacier floods

    Two British researchers recently published the first global inventory and damage assessment of the societal consequences incurred by glacial lake outburst floods (GLOFs). They revealed that glacial lake outburst floods (GLOFs) have been declining in frequency since the mid-1990s, with the majority released by ice dam failures. Glacial hazard specialists Jonathan Carrivick and Fiona Tweed…

  • Preparing Peruvian Communities for Glacier-based Adaptation

    As climate change quickens the pace at which Andean glaciers are melting, Peruvian communities located downstream from glaciers are becoming increasingly vulnerable to natural disasters. The Peruvian national and subnational governments, the Swiss Development Cooperation, the University of Zurich, and the international humanitarian group CARE Peru have executed a collaborative multidisciplinary project to help two affected…

  • Addressing Mountains in a Peruvian Village

    From 2010 to 2012, Astrid Stensrud, currently a post-doctoral researcher at the University of Oslo, researched climate change in the Colca Canyon of southern Peru, as part of the project “From Ice to Stone” from the Department of Anthropology at the University of Copenhagen. With climate change, water insecurity has caused new uncertainties for farmers…

  • Climate Refugees from the Peruvian Andes

    Two recent studies offer complementary accounts of the ways that glacier retreat and other impacts of climate change have displaced indigenous people from their communities in the Peruvian Andes. One describes the people who have left as refugees, the other as migrants. Both emphasize the seriousness and apparent irreversibility of this large population movement Teófilo…

  • Roundup: South American Glacial Research Efforts

    Glacial and Social Model of Chilean Irrigation “The model showed how external influences (globalization, climate, mountains) and complex adaptive systems (water conflicts, institutions and markets) influenced the evolution of irrigation development (the extension and emergence of novel properties) towards constructive (planned irrigation development) and destructive (climate change) futures… The model showed how external influences (globalization,…

  • Peru Faces Tensions Over Water

    Peru will face a “new normal” as greater agricultural and energy demands, population growth and climate change chip away at what is left of its glaciers, according to a recent article in the Yale Journal of International Affairs. Glacial retreat could ultimately lead to conflict in the country, the author found. “Peru offers an early…

  • Understanding Glaciers through Indigenous Cultures

    Glaciers are bound to the culture of humans who live in harmony with them and to understand the full implications of glacial loss we must include the cultural importance of the glaciers.
